The green microalgaApatococcus constipatuswas in- vestigated for its fatty acid composition using GC and MS techniques. Considerable variations were found in individual fatty acid contents according to the stage of culture development. A set of saturated fatty acid homo- logues was distinguished as the main component regard- less of the culture age. The occurrence of some uncom- mon fatty acids in minor amounts,such as hydroxylated ones,was found to be characteristic of the studied spe- cies. Depending on the development stage,those com- pounds were detected either only during initial growth phases or throughout the cultivation time.
